``Super star clusters'' (SSCs) represent an important mode
of star formation in starburst environments. Our previous
HST/FOC ultraviolet (UV) images have discovered a
sizable population of SSCs in the circumnuclear rings (radii
~300 pc) of the barred galaxies NGC 1512 and NGC 5248.
Here we present images of these systems taken with the
HST/NICMOS camera using broad-band (F160W, F187W) and
narrow-band (F187N = Paschen-alpha) filters. The near-IR
images reveal many clusters not detected previously in the
UV data. We use the observed UV/near-IR ratio to constrain
the duration of the star-formation burst in these SSCs.
Comparison of the UV and Pashen-alpha measurements allows us
to estimate the amount of dust extinction and the timescale
for the dispersal of dust and gas. The ring in NGC 1512
contains several candidate objects that resemble large-scale
wind-blown bubbles, giant shells of ionized nebulae
surrounding a stellar cluster.
